10 Best Sound Deadening Blankets 2025 in the United States

The US Cargo Control Large Sound Blanket is a sizable option designed to reduce noise by absorbing sound rather than fully blocking it. Made from a woven cotton and polyester blend with a recycled cotton filler, it offers durability and environmental friendliness. Its large size (96 by 80 inches) and weight (12 pounds per blanket) make it substantial enough to effectively dampen noises in spaces like recording studios or to help reduce sound from neighbors.

The blanket includes nine grommets along one side, facilitating easy hanging where needed. It is machine washable, although due to its recycled material, it may not be ideal for protecting light-colored items from staining. This blanket does not claim to be fire resistant, so it may not be suitable for all environments.

This product is well suited for those who need a reliable sound absorption solution and want a heavy-duty, washable blanket that’s easy to install, but it is not intended to completely soundproof a room or block noise entirely.

The JaneTech Soundproof Blanket is a heavy-duty option designed to reduce noise effectively thanks to its five-layer construction, including thick acoustic filling and waterproof outer layers. Its size (70" x 40") and weight (around 14.5 pounds) make it substantial enough to block sound, light, and even provide some thermal insulation.

The blanket stands out for its versatility: it works indoors and outdoors, resists water, and can be used in studios, offices, or even outdoor settings. Installation is straightforward with included hardware like S-hooks, wall-mounted J-hooks, screws, and anchors, making it easy to hang either temporarily or permanently. The self-adhesive hook and loop system is a useful feature, allowing you to connect multiple blankets seamlessly to cover larger areas without gaps.

The blanket is somewhat heavy, which might require sturdy support for hanging, and the dimensions might be small for very large spaces. This product suits those seeking a multi-purpose sound dampening curtain that also offers blackout and weather resistance, especially in medium-sized rooms or spaces where flexible installation is needed.

The Suvony 2 PCS Large Sound Dampening Blanket is a versatile solution for anyone looking to reduce noise. Each blanket measures a generous 96 x 80 inches, making it capable of covering large areas such as windows or doors. The material is a blend of dense non-woven fabric and synthetic cotton, which is effective at absorbing sound waves and reducing vibrations. Weighing in at 12.13 pounds per blanket, it's clear that these are sturdy and built to last, with double lock 'Z' stitching and reinforced edges enhancing durability.

Installation is a breeze thanks to the 9 metal grommets and included straps, allowing you to hang the blankets effortlessly. The blankets can be used in a variety of settings including recording studios, home offices, and even outdoors for camping or as a pet barrier. They also double as blackout curtains, furniture protectors, and more. One caveat is the initial odor due to packaging, but this can be resolved by airing the blankets out after unboxing.

The blankets are quite heavy, so handling and installation might be challenging for some. Despite this, the Suvony sound dampening blankets offer a comprehensive soundproofing solution with added versatility for various applications.
